End point prick test: could this new test be used to predict the outcome of oral food challenge in children with cows milk allergy?

摘要

BackgroundCow's milk allergy (CMA) is the most frequent food allergy in childhood; the trend of CMA is often characterized by a progressive improvement to achieve tolerance in the first 4 to 5 years of life.It has been observed that specific IgE (sIgE) towards cow's milk proteins decrease when the age increases.Although food allergy can be easily diagnosed, it is difficult to predict the outcome of the oral food challenge (OFC), that remains the gold standard in the diagnosis of food allergy, by allergometric tests.
